betakarótín

Betakarótín is a vibrant orange pigment found naturally in many fruits and vegetables. It is classified as a carotenoid, which are a group of naturally occurring fat-soluble compounds known for their antioxidant properties. Plants produce betakarótín to protect themselves from light stress and oxidation.

When consumed, betakarótín is converted in the body into vitamin A, an essential nutrient. Vitamin A plays a crucial role in vision, immune function, and cell growth and differentiation. Therefore, betakarótín is considered a provitamin A carotenoid. Common dietary sources rich in betakarótín include carrots, sweet potatoes, spinach, kale, and apricots.

The body's absorption of betakarótín is enhanced when consumed with fats. While betakarótín is generally safe, excessive intake can lead to a harmless condition called carotenemia, which causes the skin to turn yellowish-orange. This effect is reversible and resolves when intake is reduced. Supplements containing betakarótín are also available, but it is often recommended to obtain nutrients from whole foods. In high doses, particularly from supplements, betakarótín has been associated with increased risk of lung cancer in smokers.
